We look at the division of 98375237 by 816 
The aim is to understand the frequency of 816 in 98375237.

Going ahead to step 1:
If we divide 9 by 816, we get 0 and a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Include the next digit (8) from the dividend after 9, then repeat: 98 / 816

Let's proceed to step 2:
The number 816 fits into 98 0 times, leaving a remainder of 98.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 98 to get 98.
Bring next digit (3) of the dividend behind the 98 and repeat the process: 983 / 816

Let's proceed to step 3:
When dividing 983 by 816, we get 1 with a remainder of 167.
The next digit of our result is 1. 
Result so far: 1.0
The remainder is 167 after subtracting 816 from 983.
Append the next digit (7) from the dividend to 167 and continue with: 1677 / 816

Moving on to step 4:
816 goes into 1677 2 times with a remainder of 45.
Use 2 as the next digit of our solution. 
Result so far: 12.0
If we take 1632 away from 1677, we end up with 45.
Take the next digit (5) from the dividend and append it to 45, then repeat: 455 / 816

Let's proceed to step 5:
The number 816 fits into 455 0 times, leaving a remainder of 455.
The number 0 becomes the next digit in our result. 
Result so far: 120.0
Deduct 0 from 455 and we're left with 455.
Bring next digit (2) of the dividend behind the 455 and repeat the process: 4552 / 816

Step 6:
4552 divided by 816 is 5 with a remainder of 472.
The number 5 becomes the next digit in our result. 
Result so far: 1205.0
If we subtract 4080 from 4552, we get 472.
Fetch the next digit (3) from the dividend, attach it to 472 and continue: 4723 / 816

Going ahead to step 7:
816 can be fit into 4723 5 times, resulting in a remainder of 643.
Write down 5 as next digit of the result. 
Result so far: 12055.0
If we take 4080 away from 4723, we end up with 643.
Bring next digit (7) of the dividend behind the 643 and repeat the process: 6437 / 816

Advancing to step 8:
When dividing 6437 by 816, we get 7 with a remainder of 725.
The next digit of our result is 7. 
Result so far: 120557.0
If we subtract 5712 from 6437, we get 725.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7250, and continue the process.

Advancing to step 9:
The number 816 fits into 7250 8 times, leaving a remainder of 722.
Write down 8 as next digit of the result. 
Result so far: 120557.8
Deduct 6528 from 7250 and we're left with 722.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7220, and continue the process.

Let's proceed to step 10:
When dividing 7220 by 816, we get 8 with a remainder of 692.
Record the quotient 8 as the next digit in the result. 
Result so far: 120557.88
Deduct 6528 from 7220 and we're left with 692.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6920, and continue the process.

The final result is 120557.88 with a remainder of 0.692.
